Evidence First — Digital Evidence Field Guides
Menu

Vol. 1 · Computer · 2027 Edition · Forthcoming

A decision field guide for actions that can change the evidence.

Observe the state. Understand the options. Preserve what matters. Evidence First structures the decision before an intervention changes the device, the accessible state, or the options still available.

Before you act

The computer is ON. What changes if you isolate it, maintain state, acquire live, or shut it down?

Evidence First begins from the observable state and compares realistic alternatives through what each action can preserve, lose, modify, endanger, or make difficult to reconstruct. The objective is not to prescribe a universal button to press, but to make the decision and its consequences explicit.
